Description
Defines the low limit for critical speed range 2.
Note: This value must be less than or equal to the value of
22.55 Critical speed 2 high.
Low limit for critical speed 2.
Defines the high limit for critical speed range 2.
Note: This value must be greater than or equal to the value of
22.54 Critical speed 2 low.
High limit for critical speed 2.
Defines the low limit for critical speed range 3.
Note: This value must be less than or equal to the value of
22.57 Critical speed 3 high.
Low limit for critical speed 3.
Defines the high limit for critical speed range 3.
Note: This value must be greater than or equal to the value of

High limit for critical speed 3.
Activates and selects the mode of the motor potentiometer.
See section DC voltage control
Motor potentiometer is disabled and its value set to 0.
When enabled, the motor potentiometer first adopts the value
defined by parameter 22.72 Motor potentiometer initial
The value can then be adjusted from the up and down
sources defined by parameters
source and 22.74 Motor potentiometer down
A stop or a power cycle will reset the motor potentiometer to
the initial value (22.72).
As Enabled (init at stop
potentiometer value is retained over a power cycle.
Whenever another reference source is selected, the value of
the motor potentiometer follows that reference. After the
source of reference returns to the motor potentiometer, its
value can again be changed by the up and down sources
(defined by 22.73 and 22.74).
Defines an initial value (starting point) for the motor
potentiometer. See the selections of parameter
potentiometer function.
Initial value for motor potentiometer.
Selects the source of motor potentiometer up signal.
0 = No change
1 = Increase motor potentiometer value. (If both the up and
down sources are on, the potentiometer value will not
change.)
